Graduation season hits event vendors hard, and the good ones book out fast. If you want a custom balloon arch and photo backdrop, you need to lock in your date at least six weeks out before prices jump and calendars fill up completely.
A standard custom setup runs about $600. Giving yourself a clean payoff plan means you can secure your vendor today without draining your immediate cash flow.
Remember that a 0% interest window is a payoff deadline, not free money. If you still have a balance on your Discover it® Cash Back card after 15 months, standard interest rates will apply to whatever is left, so stick to your $40.00 monthly plan.
